basswork

I recently bought a Bass Pod Pro. It's a very interesting unit. When I test it with the bass going into the Bass in and listening through headphones, it performs well. However, I can't seem to gt it to work in my signal chain with my amp. For my setup, it would be great to use it in the Amp (Eden WT800) effects loop. So far I have not been able to use it this way. Any suggestions? Thanks!
